A Relational Time in Loop Quantum Gravity and Cosmology via the Drift-Time Operator

This Zenodo deposit aggregates all materials necessary to reproduce, verify, and extend the study “A Relational Time in Loop Quantum Gravity and Cosmology via the Drift-Time Operator” (Anonymous Author, August 3 2025). It provides comprehensive resources for both Loop Quantum Cosmology (LQC) and Loop Quantum Gravity (LQG) implementations, along with cosmological analysis pipelines. Contents Manuscript PDF (“drift_in_lqb_3.pdf”) presenting the theoretical framework, numerical methods, and cosmological implications. GPU-accelerated LQC scripts and Jupyter notebooks (CuPy/Python) for evolving the drift-time operator on a 150 000-point adaptive grid with holonomy corrections. Sparse-matrix codebase (Python/C++) to define and evolve the drift-time operator on a 512-node cubic spin network. CLASS configuration files and post-processing scripts for computing CMB temperature (TT) and polarization (EE) power spectra over scalar-to-tensor ratio r ∈ [0.028, 0.036] and spectral index nₛ ∈ [0.958, 0.972]. High-resolution PNG figures extracted from the manuscript, including bounce dynamics (Figures 1–2), spin-network state norms (Figure 3), and power-spectrum deviations (Figure 4). A detailed README.md covering environment setup, dependency installation, usage instructions, and reproduction steps.
